Answer :
Sure, let's go through each part step-by-step:
1. Cups of Sugar for 15 Servings:
- The recipe requires 3 cups of sugar for 5 servings.
- To find out how much sugar is needed for 1 serving, divide 3 cups by 5 servings:
[tex]\( \frac{3}{5} = 0.6 \)[/tex] cups per serving.
- To find out how many cups are needed for 15 servings, multiply 0.6 cups per serving by 15 servings:
[tex]\( 0.6 \times 15 = 9 \)[/tex] cups.
- Therefore, 9 cups of sugar are needed for 15 servings.
2. Sale Price of the Shoes:
- The original price of the shoes is [tex]$80, and they are on sale for 25% off.
- First, calculate the discount:
25% of $[/tex]80 is [tex]\( 0.25 \times 80 = 20 \)[/tex].
- Subtract the discount from the original price:
[tex]\( 80 - 20 = 60 \)[/tex].
- The sale price of the shoes is $60.
3. Percentage Score on the Quiz:
- A student scored 18 out of 20 on a quiz.
- To find the percentage score:
[tex]\(\frac{18}{20} \times 100 = 90\%\)[/tex].
- Thus, the student's score is 90%.
I hope this helps you understand how to solve these types of problems! If you have any further questions, feel free to ask.
